What are the Blockchain Apps?

Blockchain apps or DApps are decentralized applications which mean there is no intermediator to control transactions between the users. Whether it is an exchange of messages, money, or data. Due to which, its possibilities of use in different industries extended to the next level and it turns out to be a relevant option for many businesses.

In a blockchain network, all the members behave like users and mini-servers at the same time. They perform data verification and its exchange within the network. To better understand the working of the blockchain working keep on reading.

How DApps Work?

Before knowing the working of DApps, it is important to understand the working of blockchain.

A blockchain is a network of members where all the data is shared among its members. The data here is chronologically stored in blocks. Once any transaction or data exchange takes place in a blockchain network, everyone will have a record or copy of this action on their own devices.

These data blocks are associated with a chain and once they are linked to the chain, no one can make changes to it. That is why a blockchain is extremely volatile and hard to steal data from it.

Setting up a blockchain requires enough storage space (from a few gigabytes to a terabyte). So one can’t develop a blockchain in a mobile device since it does not contain that much storage space.

Blockchain can be classified into two types based on the type of network.

#1 Permissionless Blockchain

It is a kind of blockchain that is accessible to all the members of the network and available to their own devices. Every member in the network has the right to access the code, verify transactions and interact with others while keeping their identity unknown. Bitcoin is the perfect example of permissionless blockchain.

#2 Permissioned Blockchain

A blockchain that allows only authorized users known as permissioned blockchain. In this blockchain network, every member has their roles and permissions. Not even this, this blockchain is regulated by a definite set of rules for transactions between the network members. The adoption of this kind of blockchain can be witnessed majorly for managing operations within organizations.

What are the Benefits of Blockchain Apps?

Blockchain apps are gaining popularity since they offer an anonymous and secure platform. Other than this, there is much more that encourages businesses towards the adoption of blockchain technology.

  • Public Verification: Peer users of a blockchain who are also known as verifiers, confirm each transaction. Through this mechanism, each user can check the working of the system.
  • Transparency: In the system, every participant on the network can see data and transactions due to a shared copy on each device. However, they are not authorized to make changes to the data.
  • Privacy: Blockchain is a decentralized system with a higher level of transparency. Still, all the interactions and transactions between network members remain anonymous.
  • Integrity: There is surety with the blockchain that no data will be changed.
  • Easy Transactions: with the blockchain apps, it became easier to set up a wallet and start transactions using cryptocurrency without any additional fees. Whereas many banks face issues in the transaction process using mobile services and the reason behind handling the rejected transactions, commissions, and exchange rates.
  • High Security: Banking apps and messaging apps are prone to face security issues. Since it is easier for hackers to enter the system through a man-in-the-middle (MITM) attack during the transaction and steal money. Whereas with Bitcoin, there is no such risk of hack since all the data here is decentralised and every member throughout the chain shares a copy of the data.
  • Great Cryptocurrency Exchange Experience: Dealing in cryptocurrencies is quick and easier using mobile services. Besides, the market is extremely volatile and witness frequent changes in prices. The cryptocurrency exchange development market has a lot of potentials that increases the popularity of cryptocurrency exchange apps.
